Consistency is dramatically overrated. We all read through comment threads on HN where each is written in it's own style and nobody has a problem understanding it. I read through open source repos all the time, which all have their own styles and which are often not self-consistent; my comprehension is not impaired. I have worked with teams that enforce linting with a religious fervor and teams where anything goes. The anything goes team is probably more productive and with a comparable rate of bugs (but I don't have the metrics to prove it). Personally, I don't feel like my comprehension is better or worse in one setting or the other.

The difference I do notice is that when there are no linters, nobody wastes time trying to figure out how to work around it for a few lines. A great example is Eigen matrix initialization through the stream operator overload [1]. You really want to manually format that so each row is on it's own line. If you use clang-format in such code, it will be littered with

    MatrixXf mat(2, 2);
    // clang-format off
    mat << 1, 2, 
           3, 4;
    // clang-format on
